I am currently using my Magellan Sport Track Pro Color from 2000. It has all my mushroom locations along with what they are, like blacks or yellows. I am looking to upgrade and want something that is cloud based, and I can see all of my locations at once. Can My I phone and google maps do this? The last GPS i considered buying was a Garmin Oregon 600T. My old gps takes forever to locate itself and it uses a serial port cable. You have to connect it to a computer and load the map you intend to use. No computers have a serial port anymore. I can no longer do all of that. Any suggestions? I would really like to use my I phone I just dont know what app or if it will work with no cell reception.
